48 DESCRIPTION OF SPECIES. 



are related to M. alternans, Heer, l. c, p. 20, pi. iii, figs. 2, 4. They may rep- 

 resent one of these species; but on account of the simple curves of the 

 veins close to the borders, and also of their position close to each other, 

 they do not appear to be referable to Magnolia. The petiole is not inflated 

 as it is often in Ficm, but the lower pair of veins is more oblique, and, as 

 seen in fig. 6, the medial nerve is narrowly split or channeled in the middle.

Ficus Glasccena, ep. nov. 



Leaves large, thick, coriaceous, polished on the surface, oblong-lanceolate, obtusely 

 pointed, narrowing and slightly decurring to the petiole; medial nerve very broad; 

 secondary veins thin, at a broad angle of divergence, scarcely curved in passing to the 

 horders, joining without curving to it a somewhat thick marginal vein. 



The leaves are thick, 15 to 20 centimeters long, 6 to 7 broad; the 

 midrib 2 to 3 millimeters broad at base. The type of venation resembles 

 that of Ficus parasitica, Shott., as figured by self-impression in "Bil.Fl.," 

 pi. xxiii, fig. 1; the thin lateral veins sometimes branching in the middle, 

 abruptly anastomosing to a somewhat thick marginal vein which follows 

 close to the borders in successive bows. The secondary veins appear 

 separated by parallel thinner shorter tertiary veinlets; but the divisions 

 of the third order and the details of areolation are obscure.

Ficus distorta, Lesqz. 

 Plats XrV, Fig. 4. 

 Hsyden'8 "Ann. Eep.," 1874, p. 342, pi. t, fig. 5. 



Leaf coriaceous, entire, obovate, unequilateral, pointed or acuminate, apparently 

 gradually narrowed to the base; nervation pinnate; secondary nerves thick, parallel, 

 equidistant, camptodrome; nervilles strong, at right angles to the veins, anastomozing 

 and subdividing into an irregularly quadrate or polygonal areolation. 



A mere fragment of a leaf of which the upper and lower parts are 

 destroyed. The characters do not positively indicate its relation to Ficus. 

 It is figured and described for future comparison. 



Hab. — Near Fort Harker, Kansas.
